Wokin masonry core bits are ideal for drilling 4inch holes in brick, block, and concrete with SDS-Plus rotary hammer drill. Heavy duty carbide teeth break up the material more effectively resulting in up to 40% faster drilling speeds. The versatile two-piece design allows users to drill with several different core bit sizes using a single arbor. The bits we sell already include a pilot drill bit and SDS plus arbor, no need to buy extra items except the actual drilling machine. Centering pilot bit allows for easy alignment of the hole and precise spot drilling. Core bit cuts with the outer cutting edge only. The inside core must be removed to allow for deeper hole drilling applications beyond 2 inches.
